GE J AJCQ10ACC 9,900 BTU Through-the-Wall Cool Only Air Conditioner with Electronic Controls, 3 Cool/3 Fan Speeds, 282 CFM Circulation and ADA Compliant Review

GE J AJCQ10ACC 9,900 BTU Through-the-Wall Cool Only Air Conditioner with Electronic Controls, 3 Cool/3 Fan Speeds, 282 CFM Circulation and ADA CompliantNICE A/C UNIT EXCEPT FOR INCORRECTLY ENGINEERED CONTINUOUS/CYCLE SWITCH.

I BOUGHT THIS UNIT WITH THE INTENTION OF USING THE A/C UNIT IN FAN CYCLE MODE.
THIS IS WHERE THE FAN AND COMPRESSOR CYCLE TOGETHER INSTEAD OF THE FAN
RUNNING CONTINUOUSLY AND JUST HAVING THE COMPRESSOR CYCLE ON AND OFF.

THE OPERATION WOULD BE SIMILAR TO A WHOLE HOUSE A/C UNIT RATHER THAN
HAVING THE FAN RUN CONTINUOUSLY AS WITH MOST WINDOW A/C UNITS.

I DISCOVERED THAT THE THERMISTER THEY ARE USING TO SENSE ROOM TEMPERATURE
WILL NOT FUNCTION NORMALLY WITHOUT PULLING IN ROOM AIR INTO THE UNIT.
THIS HAPPENS CORRECTLY WHEN IN CONTINUOUS FAN MODE AND THE UNIT WORKS
CORRECTLY, BUT IF YOU TRY TO RUN THE UNIT IN CYCLE MODE IT FALLS FLAT ON ITS FACE,
AND WILL NOT SENSE ROOM TEMPERATURE NORMALLY SINCE THE FAN DOESN'T RUN TILL
COOLING IS REQUIRED.

I HAD THE UNIT I PURCHASED SET TO COOL AT 84 DEGREES.
THE UNIT WAS DISPLAYING A ROOM TEMPERATURE OF 75 DEGREES.
I WATCHED AS THE ROOM I WAS TRYING TO COOL WENT UP TO 88
DEGREES. THE A/C DID NOT TURN ON.I LOWERED THE SET TEMPERATURE
A DEGREE AT A TIME.. 83,82,81,80,79 ETC. TILL THE UNIT KICKED ON AT
THE DISPLAYED ROOM TEMPERATURE OF 75 DEGREES. THE FAN STARTS FIRST,
FOLLOWED BY THE COMPRESSOR A MINUTE OR SO LATER. I THEN WATCHED THE UNITS
DISPLAYED TEMPERATE ACTUALLY GO FROM 75 TO 76,77,78,79,80,81 ETC. IN A
MATTER OF 3 OR 4 SECONDS.THIS ONLY HAPPENS BECAUSE THE FAN IS NOW PULLING IN
ROOM AIR AND THE A/C UNIT SENSED THE ACTUAL TEMPERATURE.

GE NEEDS TO RE-ENGINEER THE FAN CYCLE CIRCUIT TO INCLUDE A REMOTE MOUNTED
THERMOSTAT SO THE A/C UNIT KNOWS THE ROOM TEMPERATURE BEFORE THE FAN TURNS ON
OR OTHER SIMILAR FIX. OTHERWISE IT IS USELESS IF USED IN THE FAN CYCLE MODE.
GE SIGHTS THIS MODE AS AN ENERGY SAVER MODE...THAT'S QUITE RIGHT AS THE A/C UNIT
DOESN'T START AT ALL. I HAVE THE FEELING THAT IF THE ROOM ACTUALLY ROSE IN TEMP TO
ABOUT 95 DEGREES THAT THE UNIT WOULD EVENTUALLY FEEL THAT 84 DEGREE TEMP AT THE
THERMISTER AND COME ON.... BUT THATS NOT WHAT I PAID FOR.

STAY AWAY FROM THIS UNIT IF YOU WANT TO USE IT IN CYCLE MODE, CONTINUOUS MODE IS OK.
WATCH FOR THIS SAME PROBLEM IN SIMILAR 8K OR 12K UNITS AS THEY ARE MORE THAN LIKELY
ENGINEERED THE SAME.
